I had a couple of Maple cutoffs that were splintered and had some rather long checks in them.
After cleaning up the boards, I cut them into strips making sure to orient the grain for stability. Cutting the new boards into sections and gluing them I ended up with a sizable end grain cutting board.
I like to put a 5 degree bevel on the ends so that you can easily slide chopped vegetables into your hands and it also acts as a handle so that you can easily pick up the cutting board.
I finished the board first by sanding to 240, I then raise the grain with water. Sanding again to 240.
I gave the board a healthy soak in Mineral oil and then used some Clapham’s Beeswax Finish.
